I've developed a nice visualization that is multi-touch enabled and runs on a big multi-touch display. Now we have made some experiments and placed random users in front of the application. We observed something strange. A lot of people were looking for some kind of interface such as mouse or keyboard to interact with the application.
Is there any way that I can indicate directly in my application that it is touch-enabled? It could really destroy the look & feel of the original application, but it should tell random users that approach my visualization that they should use their fingers to interact with it.
